Keil uVision 4 as Mbed debugger

21 Feb 2014

I'm using uVision 4.7 to debug my LPC1768. When I run the debugger, everything works fine except the elapse time in seconds is very off. In the register window, "sec" increases about 10 times too fast. I believe this is do to uVision believing the Mbed is running at a slower clock rate than it actually is. uVision uses the number of instructions performed to calculate the time. Does anyone know how to change this clock rate?
